Power apparatus with adjusting the rectified voltage for high efficiency wireless power transfer

摘要

The invention received wave amplitude modulation to control the duty cycle varies according to that, transmission / half-wave rectifier the AC voltage to be transmitted to the receiving end according to a rectified voltage-dependent way according to the load current for a high efficiency wireless power transfer to the load current (RAM ; the full-load load of the received wave density modulation) battery charging and all the electronic apparatus by controlling the voltages needed by the system through the method; received wave density modulation (RDM to control the density of the received wave Amplitude modulation) or a received pulse of a frequency (Full load) than the middle load or were automatically adjusted to the received voltage rectified in order to increase the medium / light-load efficiency on the receiving side in accordance with the load current increase efficiency, because many operation at light load, needed for the system at the receiving end to maintain a constant operating point of the converter for producing electrical power in particular having a stable operation and high efficiency It is a useful invention in the advantage.;
